It is not a measure of hatred, but more of a measure of motive. Motive says a big part of how that person views things (like murder, for example), and possibly if he would repeat his offense. Someone killing "just because" would more likely kill another person for the same reason then someone who got provoked to the point at which he felt there was no other way. Which offender would you feel more safe walking by? There is no question to it. The first person needs much more mental help then the second person.
